SAND-REEL APPARATUS.

Application filed February The object of this invention is to improve the construction and operation of .sand reel apparatus for oil wells and the like. One feature of the invention consists of an improved control of the apparatus from the derrick or a position near the well. The levers for such control are arranged close together in compact form so that the operator` can easilyreach and operate them, and one hand lever suflices to operate either the clutch or brake for the .Sand reel or drum or be neutral and the lever for operating the sprocket clutch of the driving mechanism is mounted on the same rod as said clutch and brake lever, and is closely associated therewith. Y f v Another feature of the invention is the particular construction for clutching the driving sprocket in the rig iron mechanismwith the band wheel; and another feature is splitting the driving clutch and brake members of the apparatus so they can be readily mounted on or removed from the' shafts.

rPhe foregoing and other features of the invention will be understood from the accompanying drawings and the following description and claims. l

In the drawings Fig. 1, is a plan view of the apparatus, parts being broken away. Fig. 2, is a view of part of the rig iron mechanism, the upper portion being in elevation,y and the lower portion in section and parts being broken away. Fig. 3 is a view of the sand reel mechanism with the frame and the upper portion being in elevation, and parts being in section, and parts broken away. Fig. 4 is a side elevation of the control and other parts of the apparatus, parts being .in section, and parts being Vbroken away. Fig. 5 is a section on the line 5,5, of Fig. 4, with parts broken away, and parts shown by dotted lines.' Fig. 6 is a plan view and section of the control on the line 6 6, off Fig. 5. f A

There is shown in the drawings `a derrick 10, which is erected over theoil well', and on which is mounted a sheave 11.4 There is also a walking beam 12, fulcrumed on a beam 112 and extending back and operated by means driven bythe shaft of the rig ircn mechanism shown on a .frame including bars 13,16 and 17. j; c Y rlfhe rig ironv mechanism has the vusual band wheel v21, which is driven by a belt ,from

an engine not shown. Said wheel has flanges 22. The shaft 20 is mounted in pillow blocks 24, which are on posts, not shown, on the timber 14. A clutch-ring 25, made in semi-circular halves, is secured to the band wheel on its right hand side by bolts 26, and ring has laterally projecting clutch jaws 27 adapted to be engaged by corresponding clutch ljaws 28 extending laterally vfrom the sprocket wheel 29, which is loosely and slidably mounted on the shaft 20. It is shown in disengaged or idle position in Fig. VA2, but is moved to the left by the collar 30 and yoked bell-crank lever 31 mounted in connection with the post which supports the pillow block 24, and is operated by a rod 32, which extends from the hand operated lever 33,

mounted inthe control frame 34, located on Y the ioor of the derrick near the well. lVhen moved to the left the sprocket 29 is clutched to the band wheel by the jaws 27 and 28 engaging each other, and then power is transmitted by the sprocket chain 35 to the sand reel mechanism.

In the sand reel mechanism there is a shaft 36 mounted at each end in bearings 37, on stands 38 extending up from the base or the angley iron frame 39. A sprocket wheel 40 is driven by the sprocket chain 35, and it is secured on the hub 41 of a clutch housing 42, that is loose on the shaft 36, and has a circumferential rim internally with which a clutch band 43 frictionally engages. The clutch band is carried by cross arms 44 and is expanded by the toggle levers 45 and 46, that are operated by the lateral movement of the clutch sleeve 47 on the shaft 36. The members 44 of this clutch mechanism are connected with the shaft, so that when the clutch operates, .power is transmitted from the sprocket 40 to the shaft 36. This clutch is 4operated by a loose collar 50, on the sleeve 47, which is actuated by a lever 51 yoke shaped and fulcrumed between its end to the' arm 52 extending from the stand 38. The lever 51 is operated by a connecting rod 53 that is'connected with a bell-crank lever 54 mounted on plate 55, as seen inFig. 4, and

which. is operated bythe rod 56 that extends tothe control mechanism at the derrick, as will be further explained.

The brake mechanism consists of the brakel wheel 60 secured on' the shaft 36and peripherally engaged by the brake band 61, see Figs. 3 and 4. Saidbrake band is carried by the stands 62, on plate 55, and is operated by the toggle construction 63 mounted on said stands 62,.,an`d operatedby a rod 64C extending tothe control mechanism in the derrick.

A able drum as usual is secured 4on the shaft 36, and consists ot a. drum 65, with flanges 66, Jfrom Twhich al cable 67 entends to the sheave il mounted on the derrick over the Well. y

The control mechanism, which is illustrated in Figs'. l, el, 5 and 6, consists of a statioiiary frame Sel', having a top plate 70, that is curved or arcuate as shown.

Near one edge this plate 70 has on it a' rack 7l. Near the bottoni the trame 3e carries a rod 72, on .vliicli the handr lever 33 is'v mounted and which opefates beside the r 7l x'nechar n inte and out o1e driving connection with the bandA oi power Wheel.` t is held in ad justed position by the spring paivl 73 and released the bellfcranltl le on the lever 38.an`d the connecting rod 7 The connect-ing rod so? controls the iriction clutchon the s'andreel mechanism and is vconnected with a short lever 76, mounted on the rod 72, see Fig. 57 which has a notched upper end adapted to receive the lia-nd lever 77, when moved to the lett-hand dotted line position, shown in Fig. 5, and it is operated by said lever 7'?. The lever 77 is mounted on the rod .72Q so as to have lateral oscillation and the arcuate plate has in it a longitudinal slot 78, through which lever 77 extends'. ln this slot there is a tongue 79 centrally located which extends partially through a slot so as to provide al passage on each side of said tongue for the lever 7'?, to hold said lever laterally when moved into the passage on either side of the ton-gue 79. lllhen the lever 7'? is inthe leithand side oi the slot 78 as shown in Fig. 5 it Will be held in engagement vvith the short lever 76 which controls the 'friction clutch in the sand reel mechanism. y l

The rod 611 which controls the brake oi tlfijefsand reel mechanism is pivoted to another short llever 80Min the trame 34 and nionted-fon the rod @and which is similar wut in-dependent of the short lever 76'. Mfsliortslever' tle op ated by 'saidhan'd 1 ver 77 'ivlren it i'st'hr'ovvi over to. the rightliand dotted vposition shown inv Fig. 5.

Inv bnilding-,tlie foregoing construction l prferably split for divide into halves the ciu ofi vfing '95; the sprocket Wheel 29 and co'fllar 50 in 'the rig iron niechanismso that they may rbe readil-'ywn'i'onnted ingplace on l ved the from without it able halves so that hey can be readily boltedon rllliis lever controls the clutch' vflnch shifts the s'proc'l t Wheel the shalt 36 or removed or replaced Without disturbing the shaft.

rlhe operati-on is as follows: y y

The cable 67 .extends from the spool oi the sand reel mechanism and passes'ov'er the sheave ll on the top ot the derrick ot the oil Well7 and it carries a bailer not shown, used to bail out the yoil Well. It is to be understood that the band Wheel is being driven continuously, Whether the sand reel mechanisi'n is in operation or not. When it is desired tofoperate the sand reel-mechanisin, the sprocket Wheel 29 on shaft 2O is clutched` With the band Wheel by operating lever '33; and said mechanism remains in operation, Without necessarily operatingA the cable' drum on shaft 86 for the sprocket Wheel 40 and clutch housing 4:2 run'v idly on said shaft, ln order to elevate the bailei-,

friction clutch e3 and 44 is operated by the hand lever 77 bei-ng moved into thelleithand' dotted line position in Fig. 5. W'hen the bailer descends in the Well, said lever 7'? moved to neutral position in slot78 in the frame Se. The cable drum thenxvill run idly and permit the bailer to descend by gravityL rl`he descento't the bailer, how ever, is retarded or controlled by the brake drum, and to do this the lever 77 is moved to the right-hand dotted line position shown in Fig'. 5.A Thus it is seenv that one lever 77 is all that is necessary to operate the entire control of the movement of the bailer or cable drum and whether the ba-iler descends or is being elevated.
